Abstract
Small parts of the electronic wavepacket of a multiply charged ion may stil l tunnel through the high Coulomb barrier for a sufficiently intense laser field of 10(15) W cm(-2) and higher. Solving numerically the corresponding Schrodinger equation, we find that the periodic recollisions of such a wave packet in the oscillating high power laser field will give rise to coherent x-ray radiation in the multiple keV regime, i.e. substantially higher than predicted or observed before.
